Lifting is all a matter of stimulus. Sprinting is the obvious king stimuli. We need to look at progression when addressing strength work. Lifting 10×10 squats might progress a 11.9 sprinter, lifting 5×5 squat might progress a 10.9 sprinter, lifting 8×2 cleans might progress a 10.4 sprinter. Its all a matter of level and can get very confusing at times.
What works for one group might not for another. Just look at the research and the researchers are typically using max a 10.2 sprinter for their studies and they’re using a spectrum of talent (10.8-10.2). Where is the sub10 research? Doesn’t exist really. Its up to these coaches to determine whats best because their athletes are always one step ahead of the research.
Charlie advocates a general to specific then back to general since sprinting becomes so intense of an activity, doing anything that resembles it at that stage only takes away from the actual sprinting work. This seems to make sense to me.
The whole “is all a matter of stimulus” thing can and is deceiving because everything doesn’t work for every person. Cleans, squats, lunges, deadlifts etc. are not the same as machine circuits, but I guarantee you when there is eventually a sprinter who runs 9.7 and does exclusively machine circuits, Charlie and whoever else will be the first to say that it is “all general.”
Writing off things as just being general takes away from specific applications of various regimes/schemes/etc. and encourages many to not work on lifting with good technique because, after all, it is just “about stimulus.”
